I'm asking because after manual fix of the file, it gets reverted back to have that bogus entry every day which kills NFS server. All clients that mount from NAS stop working
I am having this exact problem. I'm running on a brand new F8 SSD. Latest software 6.0.353-00158.
In my case, I didn't do a restore, I removed my existing shares/volumes/pool to recreate as a new pool. After doing so, I now have this invalid entry in my exports and am unable to mount anything NFS on the new shares on the new volumes in the new pool. It's not a restore file problem, it's a coding problem somewhere.
I have 30 days to return this device. Hope it gets fixed quickly. I can remove the invalid entry, but as soon as the system decides to rewrite the exports via an apply to the shares, bye bye working config. Can't have this!
